Sheet Metal Damage

If the vehicle is damaged and requires sheet
metal repair or replacement, make sure the body
repair shop applies anti-corrosion material to
parts repaired or replaced to restore corrosion
protection.
Original manufacturer replacement parts will
provide the corrosion protection while maintaining
the warranty.

Finish Damage

Any stone chips, fractures or deep scratches in
the finish should be repaired right away. Bare
metal will corrode quickly and may develop into
major repair expense.
Minor chips and scratches can be repaired with
touch-up materials available from your dealer.
Larger areas of finish damage can be corrected in
your dealer's body and paint shop.
